Circuit breaker sizing

[lmeb83]

Hello, I am looking some help with a rule of thumb or a quick way to size a circuit breaker for an enclosure that has the following power supplies. These PSU are for an HMI, a PLC and two stepper drives.
Thank you.

PSU	Inrush Current	Max Input Current (A)	Recommended Circuit Breaker
RHINO SELECT PSB series switching power supply, 48-56 VDC output, 10A, 480W, 120/240 VAC or 120-375 VDC nominal input, 1-phase	<35A @115VAC & 230 VAC	<5 A @115VAC	10A "B" Curve
RHINO SELECT PSP series switching power supply, 24-28 VDC output, 1A, 24W, 120/240 VAC or 85-375 VDC nominal input, 1-phase	NA	0.35 A	5A "C" Curve
RHINO PSB series switching power supply, 22-28 VDC output, 2.5A, 60W, 120/240 VAC or 120-375 VDC nominal input, 1-phase	<40A @ 115VAC, <80A @ 230VAC	<1.1 A@115VAC	16A "B" Curve
MEAN WELL RQ-65D AC-DC Power Supply Quad Output 5V 12V 24V 12V 4 Amp	40A/230VAC	4 A	NA
400W 60V Switch Power Supply, DC Power S-400-60 6.6A	25A/115VAC 50A/230VAC	6.6 A	NA

I typically wouldn't use circuit breakers in this application, look at 250Vac time-delay fuses like an FNM sized for 125% of full load current. If you are wanting a breaker for the cabinet containing all the power supplies, this may be useful: FAQ : How to choose Circuit Breaker? | Technical Info. | COSEL Co., Ltd.
